how to merge response array run multiple ajax calls before resolving a promise

Question

I have ajax nested in the loop. Now I want to merge the ajax returned into an array or a single object. Thanks!

$.each(res.data, function (key, value) {
    SerialNumber = value['serial'];
    Code = value['code_history'][0]['gift_code'];
    return new Promise((resolve, reject)=>{
        $.ajax({
            type: "POST",
            data: "Code=" + Code + "&action=cameraInfo_more" + "&SerialNumber=" + SerialNumber,
            url: "ajax/get-customer-info-params",
            cache: false,
            dataType: "json",
            success: function (res_more) {
                temp2 = res_more.data[0];

                //-- i want merge all json res_more to 1 array

                }
           })
        })
    })
}

Have you try with concat? . Before each loop declare empty array . let temp2 = [] and in success function . temp2.concat(res_more.data[0]); — Zar Ni Ko Ko, Aug 26 '20 at 05:02
You can push your ajax call in array and then use promise.all, to resolve it. Can you please refer answers in this https://stackoverflow.com/questions/38738614/when-all-ajax-requests-complete — bron10, Aug 26 '20 at 05:02

You're using $.each, but if you used Array.prototype.map you would end up with an array of promises. Feed that to Promise.all and wait for it to return.

Here's an example:

Promise.all(res.data.map(value => {
    SerialNumber = value['serial'];
    Code = value['code_history'][0]['gift_code'];
    return new Promise((resolve, reject)=>{
        $.ajax({
            type: "POST",
            data: "Code=" + Code + "&action=cameraInfo_more" + "&SerialNumber=" + SerialNumber,
            url: "ajax/get-customer-info-params",
            cache: false,
            dataType: "json",
            success: function (res_more) {
                resolve(res_more.data[0]);

            }
        })
    })
})).then(x => {
    console.log(x);
});

can you help me for example? – Quyện Nguyễn Văn Aug 26 '20 at 08:37 — Quyện Nguyễn Văn, Aug 26 '20 at 08:37
